badly with specimens now living, and closely resemble A. fusi- 

 formis from the Eocene deposits of Britain. 



3. Pleurotoma fusiformu was described from Mount Harris. 

 Von Haast does not mention it as coming fi'om the Waihao 

 greensands. I have collected it often, but not at the Waihao, 

 and think it should be dropped from the list. 



4. Pleurotoma buchanani. — This is mentioned by Dr. von 

 Haast as a fossil of the Waihao greensands. A distinction of the 

 Waihao specimens from those coming from younger formations 

 might be shown, but I choose to admit it a fossil of the Waihao 

 greensands. 



5. Pleurotoma awamoaensis. — This, in the first lists, was given 

 as a variety of P. awamoaensis. Why should it now be other- 

 wise ? 



6. ClatJiurella hamiltoni. — I do not know this species, and 

 accept it as coming from the Waihao. 



7. Voluta corrufjata. — That such a prominent fossil in all the 

 beds in which it occurs should be absent from the collections 

 made by v. Haast and myself, leads me to think that the 

 specimen fi-om the Waihao greensands must, in the first list, 

 have been named V. elon<jata, Hutton. I have a species of this 

 genus from the beds, but it is neither T. cornujata nor Y. elongata ; 

 therefore, until its occurrence be verified, I cannot accept V. cor- 

 ruf/ata as a fossil of the Waihao greensands ; though, at the 

 same time, I suspect that it occurs in the Oamaru formation. 



8. Natica suturalis comes from Mount Eoyal, near Palmer- 

 ston, Otago, where the beds are most certainly the same as 

 those elsewhere referred to the Oamaru formation of Hutton. 



9. Leda fastidiosa comes from beds belonging to the Oamaru 

 formation in the Trelissick Basin ; that it is recent, concerns 

 us not at the present time. 



Thus, of these nine species, there are only three that can be 

 fairly claimed as being unknown in rocks of greater age than the 

 Pareoia beds. Vleurutorna fuMformiH is very doubtfully a fossil 

 of the Waihao greensands. Pleurotoma buchanaiti and L lathurella 

 hamiltoni are, therefore, the only evidences that the Waihao 

 greensands belong to the Pareora formation. 



Are the paltpontological proofs, then, of such a character that 

 we must disregard the clear stratigraphical evidence as above 

 stated ?
